Applies to 2008-13 models

Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Infiniti EX35 was introduced in the 2008 model year and renamed the EX37 in the 2013 model year because the engine size was increased. The EX was renamed the QX50 beginning with the 2014 model year.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head acceleration from the roof/sunvisor hit was low.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head contacted the side curtain airbag, which had deployed during the crash, and the roof and sunvisor.

Two tests of 2008 EX35 models were conducted. The injury ratings for the driver are based on just the second test; measures for the driver in the first test were not obtained because of equipment failure. The injury ratings for the rear passenger and the head protection ratings for both the driver and passenger are based on both tests. Structural ratings also are based on both tests.

Injury measures

Driver — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Passenger — Measures taken from the dummies in the two tests indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — In both tests, the dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Passenger — In both tests, the dummy's head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
